My aging eyes find white lines on black background very hard to read unless the white lines are considerably thicker than they are in many diagrams. Same goes for white type on black background -- bumping up the font size doesn't help much. (Screened lines/background, any color, are even worse.)
Thanks for asking, Gerardo! And thank you, Sy, for the tips on reversing the background/foreground on webpages. The tip, "Mac users: Command + Option + Control + 8," just helped me read a white-on-dark gray webpage. Karen Karen Reeds karenmre...@gmail.com
